Question about mixing 4-pin CFL bases and lights wattages


I have recessed lights in the kitchen running triple tube CFL's which are the 4 pin style.

The bases are of type GX24q-3 which are rated for 26w bulbs and are currently running 26w bulbs.

I was wondering if I could run 18w bulbs in them without a problem (like you can normal incandescent). Or must it be 26w?

Thanks!

You can run a lower wattage without problems. The rating is the max wattage.

Question about mixing 4-pin CFL bases and lights wattages


The ballast is in the bulb (maybe not for the pin types !!)
So its easy to swap wattages

Woah .,, Woah.,,

Before you go this route please verify the ballast info if this is a hardwired CFL unit.

You can not install smaller wattage flourscent bulb without checking the ballast info.

If they can allowed smaller wattage bulb you are good to go.



Dave just give you a head up this type of socket as OP describing that is hardwired recessed luminaire so the OP have to pull the can sleeve down to see the ballast info I know it will not be easy but that is the only way the OP can verfiy the ballast info.


a7ecorsair.,

Not always the case it depending on which type of ballast if electronique or magatinc ballast if electronique it may have multi wattage rating but not on magatic they only rated for single wattage most case unless they stamp the info on that.


Merci.

Question about mixing 4-pin CFL bases and lights wattages


Interesting....all of my 4 pin recessed have the ballast built into the bulb (maybe not!)
I was unaware that any fixture had the ballast for the CFL bulbs
Or that any CFL bulb was available without a ballast built in

I have never installed or worked on a pin type CFL that had the ballast in the base.

Question about mixing 4-pin CFL bases and lights wattages


Haven't bought the lower wattage yet. I pulled down the baffle and reflector and this is the model I have:

http://www.iuseelite.com/pdf/B5PLIC_BAFFLE.pdf

Spec sheet says "Accommodates (1) 9W, 13W, 18W or 26W compact fluorescent lamp"

So looks like I should be good to go, Anything else I should be looking at?

my pdf reader isn't working right so I can't read the link but, if that label is on the ballast, then you are ok. If it is on the housing, you need to check the ballast to see what it will drive.

I just checked & mine have ballasts marked for 13w bulbs only
Good to know...I think 13w or less would be all that would fit in mine

The safest way is check the ballast info many time it will stamp the wattage on it.

If it have couple wattage listed then you should be ok.

But if you install 18 watt bulb and still look very bright then you have to revert back to 26 watter the reason why I mention that due you can overdrive the bulb and it will shorten the life of it.

Merci.
Marc
